The Blue poison dart frog

The present blue poison dart frogs habitat is in humid areas while I predict it's future habitat will be in the water because it will be to hot to live in the heat and humid areas.I predict the blue poison dart frog will adapt to living in the water and grow an air sack and they will use that to breath under water and go to land to catch prey and refill they're air sack. Another adaption they will make is they will grow veins so when they absorb water 30% percent of it will go flowing through the veins cooling down the body. I believe these adaptions will happen so it can stay cool during the heat and live in it's new environment.
